问题 The main topic of the passage is the ______.
The author implies that allelomimetic behavior occurs most often among animals that ______.
选项 A、prey on other animals
B、are less intelligent than their enemies
C、move in groups
D、have one sense organ that dominates perception
答案C
解析 此题考查学生领会作者意图的能力。解答此题须先找到有关事实，然后认真领会方可找到答案。作者暗示遗传模仿行为大多发生在群体活动的动物身上。在文章第三段最后一句话可以找到此On the other hand，such behavior is a major system among large-hoofed mammals, such as sheep.(另一方面，这种行为在长蹄的大型哺乳动物如羊群等身上最为普遍。)羊群以群体活动为主，这种行为比其它哺乳动物更普遍，因此C为正确答案。 A掠食其它动物；B不如自己的敌人聪明；D有一个支配视力的感官。A、B和D三项均不合题意。文中提到过猛禽在猎取prey ainmals(被掠食者)时也有这种allelomimetic behavior的功能，但发生在它们身上的可能性远没有发生在被掠食动物身上的可能性大。
